I’ve followed the instructions in the Build Thread: HaLow for Raspberry Pi OS thread and started out using the same pin mappings specified in the morse-spi.dts file. I’m completely new to this subject and thought the same pin mappings should work even though I’m using the Seedstudio Xiao Halow carrier board.
I did find error messages though

In searching the forums I found this issue that looks simular
My original wiring was
Reset gpio5
wakeup gpio3
spi_int gpio25
spi_cs gpio8
busy gpio7
spi_mosi gpio10
spi_miso gpio9
spi_clk gpio11
I have wired my module using 4cm dupont wires and based on the support threads probably need to solder these up.
In looking that this support thread, it suggested two pin changes, which I tried and have the same errors in the log file. Upon re-reading the support thread it seems the two pin changes are not relavent here.
I’ve tried lower the spi frequence which hasn’t made any difference. Other than soldering the leads, what else should I be looking at to resolve?
